Building Safety in Hillsboro, OR

If you live in Hillsboro or are thinking about moving there, building safety are one of those things you probably won't think about until they affect you directly. Hillsboro has 5 specific rules on the books covering different aspects of building safety, and some of them might surprise you.

Electrical Permits

Hillsboro enforces electrical work through the state-adopted Oregon Electrical Specialty Code, and any permit the City issues is void if inspection approval doesn't occur within 6 months. A voided permit can be extended once or renewed once for a 50% fee, and solar and other alternative-energy installations are exempt from the permit fee itself.

Key details: Adopted code: Oregon Electrical Specialty Code (OAR 918-305-0100). Governing section: HMC § 11.04.010(D). Permit expiration: 6 months without inspection approval. Renewal fee: 50% of initial permit fee. Alt-energy fee exemption: Permit fee waived, permit still required.

Chapter 11 sets no separate electrical-permit penalty, so a violation, working without a valid permit, or continuing work after a permit has voided under § 11.04.020(A), falls under the Code's general penalty in HMC § 1.08.010(B): a $500.00 fine, with HMC § 1.08.030 making each day of continued unpermitted work a separate $500.00 offense.

Plumbing Permits

Hillsboro enforces plumbing work under the state-adopted Oregon Plumbing Specialty Code, and any plumbing permit the City issues expires if inspection approval doesn't occur within 6 months. A voided permit can be extended once or renewed once for a 50% fee before it must be reapplied for from scratch.

Key details: Adopted code: Oregon Plumbing Specialty Code (OAR 918-750-0110). Governing section: HMC § 11.04.010(C). Permit expiration: 6 months without inspection approval. Renewal fee: 50% of initial permit fee. Alt-energy fee exemption: Permit fee waived for qualifying installs.

Chapter 11 sets no plumbing-specific penalty, so unpermitted plumbing work, or work continued after a permit has voided under § 11.04.020(A), falls under the Code's general penalty in HMC § 1.08.010(B): a $500.00 fine, with HMC § 1.08.030 treating each day of continued unpermitted work as a separate $500.00 offense.

Building Permits

Hillsboro requires building permits under a set of state-adopted specialty codes covering structural, mechanical, plumbing, electrical, residential, manufactured dwelling and energy work, and every permit voids if inspection approval doesn't occur within 6 months. A voided permit can be extended once and renewed once for a 50% fee before it must be reapplied for.

Key details: Governing section: HMC § 11.04.010. Codes adopted: 8 Oregon specialty codes (2014). Permit expiration: 6 months without inspection approval. One extension: 6 more months, Manager approval. Renewal fee: 50% of initial fee, within 6 months.

Chapter 11 relies on the Code's general penalty for building permit violations: HMC § 1.08.010(B) sets a $500.00 fine, and HMC § 1.08.030 makes each day that unpermitted or voided-permit work continues a separate $500.00 offense. A building erected, altered or maintained in violation of the adopted specialty codes can also be pursued as a dangerous building under HMC Subchapter 11.08.

Building Inspections

A Hillsboro building permit expires if no inspection approval occurs within 6 months of issuance, though each approved inspection automatically extends it another 6 months under HMC 11.04.020.

Key details: Citation: HMC § 11.04.020. Expires after: 6 months, no inspection. Auto-extension: 6 months per approved inspection. Manager extension: One 6-month extension, written request. Renewal fee: 50% of initial permit fee.

An expired, uninspected permit voids all further work until a new permit issues; continuing work under a void permit is a code violation subject to HMC 1.08 general penalties.

Childcare Center Rules

Hillsboro's Community Development Code sets siting standards for child care facilities, including a required sight-obscuring fence and street-frontage rules for facilities in residential zones.

Key details: Governing section: CDC § 12.40.150. Play area fence: 4 to 6 feet, sight-obscuring. Small-home exemption: 16 or fewer children (ORS 329A). Residential siting: Collector or 2 route-street corner.

Building/site plans that omit required drop-off capacity, play-area fencing, or the required street-frontage location can be denied approval or conditioned by the Review Authority under CDC § 12.40.150(D).

The Bottom Line

Hillsboro's building safety rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Hillsboro is broadly strict or permissive.

These rules come from Hillsboro's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
